ISIDORE MUND AND MEYER STARR, OF DETROIT, MICHIGAN.

CHECK-PROTECTOR.

Application filed September 9, 1920.

To all whom t 'may concern Be it known that we, lsiDoRn MUND and MEYERSTARR, citizens of the United States, and residing at Detroit, county ofl/Fayne and State of Michigan, have invented a new and improvedCheck-Protector, of which the following is a specification.

rThis invention relates to means for perforating, imprinting orembossing checksy and other commercial papers with numerals, letters orother characters in such a manner that the sum or amount indicatedthereby cannot be varied, and its object is to provide a simple andeffective protecting mechanism of such small size that it may be carriedin a coat pocket, and which shall be so simple in construction that itcan be produced at low cost.

This invention consists of a case and a guide therein, a series ofchains slidable around the guide, each link being provided with a raisedcharacter, means to move the chains independently7 of each other, and aplaten hinged to the case and provided with a row of dies adapted tocooperate with the characters on the links to emboss, perforate orotherwise multilate the commercial papers which are placed upon theplaten.

It further consists in the details of con-- struction illustrated in theaccompanying drawings and particularly pointed out in the claims.

ln the drawings, Figure 1 is a side and Fig. Q an end elevation of thisnovel perforating device. Fig. 3 is a 3 3 of Fig. 5. Fig. 3 is a detailof the chain guide on a larger scale. Figt is a section on the line 4 4:of Fig. 3. Fig. 5 is a plan of the device. Fig. 6 is a plan of a part ofthe platen with the dies removed. Fig. 7 is a perspective of one of thelinks. Fig. 8 is a plan of a perforating die on a large scale. Fig. 9 isa view similar to Fig. 1 with the case swung up- Similar referencecharacters refer to like parts throughout the several views.

The case shown in the drawings comprise a top 1 and the sides 2 betweenwhich eX- tends the tubular guide 3 for the chains 4f. The metal of thisguide may be struck up at intervals to constitute the lips 5 betweenwhich these chains are slidable, as shown in Fig. 4. Each chain ispreferably built up of ten links 6, one for each digit, but anyadditional number of links can be provided for if additional charactersare to Specification of Letters Patent.

' be used. Each link preferably provided with a transverse notch 7 toreceive the alinng rib 8 on the guide; although this alining device maybe omitted, as shown in Fig. 7, we prefer to form the link withperforated ends 9 adapted to extend between the ears 10 of the neatadjacent link and be attached thereto by means of pins 11.

l shaft 13 entends across within the case and supports the star-wheels14 whose 'teeth entend out through the opening 15 in the case and alsoextend into the inclined-sided notches 16 in the links. These teethenable the wheels to be turned and the chains to be slid around on theguide 3 to bring any desired links in alinement with the dies on theplaten. rlhe rib 8 is Ytermed on the guide to properly aline theseselected links as indicated in Fig. 3u.

At the end of the case opposite the shaft 13 is a hinge 18 on which ismounted the platen 19 in the form of a fiat plate across which entendthe bars 2O and 21. A spring 23 tends to swing down the platen, but'this is normally prevented by the latch ii resilient rectangular frame25 is attached to the cross bar 20 for the purpose of stripping theperforated paper from the characters on the links, when the machine isconstructed; for perforating- Any desired devices may be employed toimpress the desired characters on the paper. Those shown consist ofnumerals formed ot short sections 95 (Fig. 7 each constitutingl a punchadapted to enter one of the hclcs 27 in the die 28, the various numeralsbeing so formed that portions thereof will register with these holes 27in such a manner that any desired ligures can be indicated byperforations. @ne of these dies is secured to the holder 21 therefor foreach chain 6 and is so positioned that it will register with thecharacters on the links when the links are alined by the rib 8 on thechain guide. Short partitions 30 on the die holder 21 hold these dies inproper position. It will be understood that any other impressing orembossing mechanism in common use may be substituted for theseperforating devices which are preferred as no inking mechanism isrequired.

In Fig. 6 we have indicated the words Pay and Only as examples ofletters or characters which may be impressed on the commercial papers atthe ends of the amounts, but these as well as all the details ofconstruction may be varied by those skilled in the art without departingfrom the spirit of our invention as set forth in the following claims.
